The user defines the boundary polyline that they have drawn to outline the GeoFluv™ design area on the drawing. GeoFluv™ will automatically calculate and display the watershed area inside the defined boundary. (This area is only the area to which the GeoFluv™ design will be applied. If additional undisturbed or previously reclaimed area lies upstream of the GeoFluvTM design area, runoff from that additional area can be added into the design in the Channels tab using the Add Area window.) The default area units are acres, but metric units can be selected in the Carlson Drawing Setup dialog box accessed through the Carlson toolbar at Settings/Configure /Drawing Setup (use of consistent units in a drawing is recommended).
Command Prompt:
Select GeoFluv boundary polyline. Select objects
The user moves the cursor to cross the GeoFluv Boundary polyline anywhere along its length and left-clicks to define the GeoFluv Boundary to the Natural Regrade module.
The command prompt reads, “New GeoFluv boundary has been accepted.”, if the cursor has clicked on a closed polyline, the watershed area is calculated and displayed, and the Select Main Channel button on the Setup tab becomes active. The command prompt reads, “GeoFluv boundary polyline must be closed.” if the polyline the user selected is not closed, and the watershed area is not calculated and displayed, and the Select Main Channel button remains inactive.
